Rob Devinney, a Virginia Beach-based event promoter, has put together an ambitious, two-day, indoor music festival that will feature as many as 55 local bands as well as out-of-town acts Mansions on the Moon and Life on Repeat.

The list of standout area musicians playing the for-charity event includes The Fuzz Band, Session Rockers, Phillip Roebuck, Major and The Monbacks, Freedom Hawk, The Kill Circuit, The Nerve Scheme, Shakespeare's Ghozt, 710 Oil, family Tree and Alpha Whale. Music will be presented on as many as five stages. See the full list below.

Mansions on the Moon, an electronic rock quartet, has roots in Virginia Beach but is now based in Los Angeles. Its 2012 EP "Lightyears" was executive produced by Pharrell Williams and the group has toured with Mac Miller and Wiz Khalifa.

A $15 ticket purchased at the door gets you into the Music 4 More Festival both days. Advance tickets can be purchased from the VA Live website.

What's the motivation for this musical frenzy? Devinney, who does promotions for Firefly vodka, has linked up with Music 4 More, a Baltimore-based charity that helps find instruments for struggling school music programs across the nation.

"The music program at Oscar Smith Middle School is in dire need of help," Devinney said. "We want to help get them the new instruments they need to get the program up and running ... We need to raise close to $4,000. That's our goal. I'm confident we'll get that."

Most of the acts performing are donating their time and talent to the cause, Devinney said.

"I was in a school band," he said. "If I wasn't, then I wouldn't have ended up the person I am today. Music is really important."
